Assessing the Effects of Varying Lead Concentrations on Tomato Plant Growth and Physiological Parameters

The purpose of this research was to look at the impacts of lead (Pb) contamination on the physiological and morphological parameters of tomato plants (lycopersicon esculentum) developed in soil with distinctive Pb concentrations (50, 70, and 90 mg/kg dry mass of soil). This experiment was carried out in a clay pot by planting tomato seeds in soils contaminated with Pb concentrations (50, 70, and 90 mg/kg soil) and at that point observing the tomato plants development parameters at three vital stages: 18, 36, and 54 days after sowing (DAS). Different physiological (chlorophyll content, leaf area index, and relative growth rate) and morphological (plant size, leaf number, number of branches, root length, number of fruits, and biomass) parameters were measured to assess the impact of Pb toxicity quality. All measurements were appeared to be altogether affected contrarily, with development and physiological capacities being more severely decreased at higher Pb concentrations (70 and 90 mg/kg dry mass of soil) than at the control and lower measurements (50 mg/kg dry mass of soil). The plants subjected to Pb concentrations at 54 DAS showed signs of stunted growth, reduced chlorophyll content, poor the photosynthesis process, and reduction in total biomass, highlighting the detrimental effects of Pb contamination on tomato growth output.
